Screen flickers when switching windows on MacBook

I was very lucky to encounter a rare nuisance. When I switch anything in the browser, my screen flickers. Either blue or pink is included but most often pink colour.

How this happens:

1. I go to any site with a predominantly white background

2. I open a pop up that obscures the main part of the website.

> 2.2. It doesn't have to be a pop-up. It can also happen in Figma if I turn off the gray layer

3. I close the pop-up and at this moment flickering occurs

I recorded a video for demonstration. I'm sorry my iPhone blurred everything but that doesn't interfere. In video, I opened two programs, Safari and TextEdit

Safari is on the left, where I open and close the popup. When closed, the entire screen flickers:

MacBook model: M3 pro 2023, 18/512, Sonoma 14.5

I've been using it for 2 months. As I said this happens when switching the interface in all my browsers. But I tried in Photoshop (for example) and couldn’t reproduce it there.

I carried out diagnostics using the Apple Diagnostics program (Apple Hardware Test). Diagnostics didn't reveal any problems. Then I reset my Mac but it didn't help me. The video shows a clean MacBook on Sonoma 14.5.

The MacBook isn't supported in my country. What can I do to fix this?
